Described as "zesty, citrus-laced and massively refreshing", Elvis Juice is the 6.5% ABV revamped version of a prototype grapefruit beer from last year.
"[Elvis Juice] pays homage to the hop character that we have in a lot of our beers, which is very grapefruity," Sarah Warman, BrewDog head of marketing, said.
"To bring this to the fore, we add bags of grapefruit peel during the brewing process to enhance the flavour."
Released alongside Elvis Juice is the first beer from the Ace of Hops limited series of a 4.5% ABV single-hopped session IPAs.
Beginning with a celebration of the Simcoe hop, the Ace of Simcoe beer has a "kick of resinous pine, backed by floral apricot and deeper passion fruit flavours".
Throughout the year, other "hop salutes" will follow, showcasing Chinook, Citra and Equinox, as Warman explained: "Our series of single-hopped beers, which is something we're really excited to showcase. We've found that a lot of people are really interested in experiencing single hops on their own so that when that hop is present in another beer they can pick it out."
Both are available in BrewDog fridges now with draught to follow in a couple of weeks. They will also be widely available throughout the on-trade with major listings already secured.
Later in March, the Scottish brewery will also launch Hammer Heads – a spin-off series of its popular Jack Hammer beer.
"We're always experimenting, always trying to bring something new to the market, which is summed up by this upcoming series," Warman said.
Named Monk Hammer, Black Hammer and Rye Hammer respectively, the brewery will showcase how they can take a single brew in a number of different directions.
The addition of Belgian yeast to the malt bill will be the first point of difference in debutant, Monk Hammer.
Other notable brews expected during the next two months include Protoköl, the second Kölsch-style ale after the release of No Label, and a re-brewed version of Clown King barley wine, along with upcoming collaborations with Floridian microbrewer J Wakefield and San Diego-based brewing company Ballast Point.
Both Abstrakt and Dog series of beers will also receive an updated edition.
